Do they collide or merge to become bigger or, do they repel each other like magnets. Is there any proof of either? What happens to matter in theory when it enters a black hole.

Hello, I was watching a television show last night on mega black holes and the mystery around how they were created...They found balck holes in the center of every galaxy.

Nobody mentioned this on the show, but I am wondering, has anyone ever considered that they could have been created by the big bang for our galaxy, but big bangs for every galaxy....?

Here is why I am asking....If you look at what happens in a nuclear explosion, things get shot away, then they start recoiling back. Kind of like dropping a stone in the middle of a bowl, the wave eventually comes back to the center..

I know that there is something wrong with my thought because these physicist already looked at it as being a possibility and dismissed it.

Does anyone know why it is not plausibile?
